ISLE OF DOGS Patricia Cornwell's novels of big-city police have taken this classic genre to a new level. "Move over, Carl Hiaasen, you've got company," the San Francisco Examiner warned. "Patricia Cornwell has switched  to Hiaasen's world of black humor and nearly conquers it." USA Today concurred: "Cornwell has coined a new penny." With Isle of Dogs, Cornwell outdoes herself with a wry tale of life and turmoil behind the blue wall.   Chaos breaks loose when the governor of Virginia orders that speed traps be painted on all streets and highways, warning that speeders will be caught by monitoring aircraft flying overhead. But the eccentric Isle of Tangier, fourteen miles off the coast of Virginia in the Chesapeake Bay, responds by declaring war on its own state. Judy Hammer, newly installed as the superintendent of the Virginia State Police, and Andy Brazil, a state trooper and Hammer's right hand and confidant, find themselves at their wits' end as they try to protect the public from the politicians-and vice versa-in this pitch-perfect, darkly comic romp. With a Swiftian eye for the absurd and dead-accurate aim on her targets, Cornwell delivers another knowing story of the lives of the men and women in blue.
